NUMTs in the Brain (IMAGE)
Caption
Mitochondria release segments of mitochondrial DNA that can travel through pores of the nucleus and integrate into a cell's chromosomes (where the insertions are called NUMTs, for nuclear mitochochondrial segments). A new study has found that nuclear mitochondrial DNA insertion—once thought rare—happens in the human brain likely several times over during a person’s lifespan.
